e24086 Background: Nasal vestibulitis has been infrequently described as a side effect of cancer-directed therapy; however, a preliminary study reported that 71% of patients undergoing taxane chemotherapy experienced nasal vestibulitis symptoms. This natural history trial describes the incidence, characteristics, and severity of nasal vestibulitis symptoms among patients undergoing paclitaxel, docetaxel, and non-taxane chemotherapy. Methods: Eligible participants who reported baseline (prior to starting chemotherapy) nasal symptoms ≤ 2 on a 10-point scale were enrolled in this trial upon initiation of a new treatment regimen, involving paclitaxel or docetaxel, or non-taxane chemotherapy. Participants completed nasal symptom logs each time they received a dose of therapy until either the regimen was stopped or four months had passed. The proportion of patients reporting new nasal symptoms was estimated within each cohort with the 95% exact confidence interval (CI). A cumulative incidence model was utilized to quantify the incidence of treatment-emergent nasal symptoms within each cohort, while controlling for age, sex, smoking history, and history of asthma or allergies. Results: Thirty-five participants received paclitaxel, 21 received docetaxel, and 25 received other types of chemotherapy. 86.4% of participants were female, mean age was 60.2 ± 11.2 years; 93.8% of participants completed 2 or more surveys. A higher percentage of participants in the paclitaxel cohort experienced new nasal vestibulitis symptoms than participants in the other two cohorts. The percentage (95% CI) of participants with nasal symptoms, for patients receiving paclitaxel, docetaxel, and non-taxane chemotherapy were 74.3% (56.7%, 87.5%), 47.6% (25.7%, 70.2%), and 44.0% (24.4%, 65.1%), respectively. Epistaxis was reported by 60% of participants in the paclitaxel cohort. Paclitaxel-receiving participants also reported nasal dryness (48.6%), scabbing (40.0%), and pain (20.0%). Nearly half of participants reported moderate symptoms (4-7 out of a 10-point scale), with 8.6% reporting symptoms as severe (8-10 on a 10-point scale). Conclusions: Nasal vestibulitis is a common side effect of chemotherapy, especially paclitaxel chemotherapy.

e14018 Background: Cancer survival rates are improving. Therefore, management of cardiovascular complications has now become a crucial clinical concern. Cardio-oncology is the sub-specialty that assists in the overall management of cancer patients in a multi-disciplinary manner. Mayo Clinic cardio-oncology practice was initiated to work closely with our oncology colleagues for early detection of cardiovascular complications in response to cancer-therapy. Majority of the patients visit our cardio-oncology clinic once, we thought it is important to study the group of patients that visited frequently due to cardiovascular complications. Aim: To evaluate the most common cardiovascular complication in patients with 2 or more visits to our cardio-oncology clinic. Methods: From 2012-2017, there were > 2500 patients visits to our clinic, with 24 patients having 2 or more visits. Data including patients’ demographics, ethnicity, chemotherapeutic medications, primary cancer type, cardiovascular risk factors, echocardiography and clinical outcomes were collected. Cardiotoxicity was defined as the decrease in left ventricular ejection fraction (LVEF) of > 10% to a value of < 53%. Heart failure was diagnosed based on Framingham’s criteria or by a cardiologist. Results: There were 19 women (80%) and 5 men (20%). Median age at the time of diagnosis was 56 years [19-76]. The most common malignancy was breast cancer (70%), followed by B-cell lymphoma (12%) and acute myeloid leukemia (8%). Thirty percent had > 2 risk factors for cardiovascular disease. 75% of the patients had an LVEF of < 53, of these 67% developed heart failure with 58% preserved and 42% reduced ejection fraction. Those with heart failure had received a mean anthracycline dose of 305 ± 91.8mg/m2. With initiation of ACEI, B-Blockers, and diuretics (GDMT) 79% showed recovery of LVEF to ≥53 during the follow up. Conclusions: In our experience, most patients who were seen at least twice in the cardio-oncology clinic for heart failure had received a dose of > 300mg/m2 anthracycline. With GDMT over 75% of the patients recovered. Care in the cardio-oncology clinic plays a key role in optimizing these clinical outcomes.
